Nouveau Now Supports Overclocking Your GPU

Phoronix: Nouveau Now Supports Overclocking Your GPU

While the Nouveau driver may not yet have a stable Gallium3D or DDX driver release nor does it have capabilities like stabilized power management or OpenGL 3.x, if you want to overclock your NVIDIA graphics card with this open-source driver, you can now do so today. Martin Peres who has been working on Nouveau power management support and timing management, has produced a patch to support custom clock manipulation of the NVIDIA graphics card's core clock, memory clock, and shader clock speeds. The voltages can also be manipulated too whether you are manually overclocking or underclocking your GPU with this Linux kernel DRM driver...

I want such things inside the kernel! maybe it's not useful yet but open source is about choice so I want the choice to fry my entire hardware.
And you can do very very useful things with this. I can get an hour of extra battery-life out of my laptop thanks to phc. It's a shame kernel devs are against such things.

I'm still waiting for controllable fan support in nouveau cause without this my graphics-card is unbearable.

The comment about nv84 and nv86 is about another patch I haven't released yet, I'm still working on stabilizing it and make it regression-free (ie, not break cards that used to kind of work if the stars were aligned properly).

While profiles are great, most people want dynamic power management. This is something I would like to add but there is a lot of Reverse Engineering to be done first.

Ragas: Fan control may already be there, you can PM me or come on #nouveau. Anyway, two people are working on that (temperature and fan management). Anyway, if the support is not here yet, I have some things I would like you to test

You obviously didn't read the article. The patch is by a company that specialized on using GPUs for general purpose computing, not games.

Actually, I'm not from PathScale, I'm just an CS student. I'm just helping them where I can.

This patch was first made for reverse engineering/debugging purpose. It also allows people to overclock their card, but it is more of a side effect

You can use this patch for improving the FPS rate, but don't expect too much of it, the gallium driver seems to have a serious bottleneck which makes overclocking on my computer pretty useless (62 -> 73 fps in openarena). It is already being worked on.
